Yeah, I like to break up my work day too. I work 15-20 minutes at a time, then take a 5-10 minute break. Not very efficient, I know, but it's better than me staring at a computer screen for 3 hours straight not being able to get ANYTHING done. Hell, sometimes I'll take a 1-hour nap if that's what I need.

When I'm depressed, I just have too much difficulty staying on track because my concentration sucks, so I don't have any real advice there. I just sulk all day.

With hypomania, I'm so distracted because I have racing thoughts. It's like there's a TV turned on in my head and someone is constantly flipping the channels.

ADHD treatment can help, but stimulants just make me hypomanic or manic (depending on how much I take at once). So you have to be wary of that too. I've tried non-stimulant treatment, but from my personal experience, they kinda suck.
